The data document the results of several microbe bioassays performed by the USGS on Phragmites australis plants, including those performed on mature leaves, seedlings, and dead leaf tissues exploration of the literature to find accounts of microbes associated with Phragmites worldwide. For the bioassays, we prepared 162 pure cultures isolated from Phragmites plants in North America along the east coast, Florida, the Gulf of Mexico, and the Great Lakes area, 125 of which were from a previous study, and 38 represent new collections. The DNA sequences used to identify the 37 new collections are included. Microbes were isolated from plants collected from 2015-2018. We performed assays using both North American plant...
This dataset includes benthic algae community composition data from three sites in the upper White River Basin, Colorado, in 2022. Benthic algae were identified as genus or species, and biomass and biovolume were provided for taxa.U.S. Geological Survey completed data collection in upper White River Basin in cooperation with the White River Conservation District. Data collection was funded by the U.S. Geological Survey Water Mission Area as part of the Next Generation Water Observing System Upper Colorado River project.
Longstanding taxonomic uncertainties have limited conservation efforts for species currently assigned to the freshwater mussel genus Alasmidonta. Here, we present mitochondrial and nuclear DNA sequence data needed to assess the genus- and species-level taxonomy of Alasmidonta. These molecular data allowed us to test whether cryptic diversity exists within Alasmidonta and whether A. triangulata and A. arcula are distinct species. Details associated with specimens and DNA sequence data are provided here to provide a foundation for future research on Alasmidonta and give conservation agencies greater confidence in the findings of our work.

These are genetic data collected from replicated samples of 21 Enteroctopus (E. dofleini or a cryptic lineage) in Prince William Sound Alaska to evaluate tissue type, DNA extraction method, and time until analyses are completed on data reliability. Data collected from all samples include two microsatellites identified as possible lineage indicators, and nine microsatellite loci previously identified as polymorphic in both lineages. DNA sequence data from 528 bp of the octopine dehydrogenase (OCDE) gene were also collected.

List of all plant species found in, or adjacent to, plots K1 or K2 during all the sampling periods. Species recorded at least once during the vegetation transect surveys are marked with “Yes”. The taxonomy follows Wagner and others (2005).
This dataset includes benthic algae community composition data in the Colorado River near Cameo, Colorado, U.S. Geological Survey (USGS) site number 09095500, from 2022 to 2023, and from three sites in the upper White River Basin, Colorado, in 2022. Taxonomic classification of algae species is not known well in theses rivers, and this study was conducted to record different algae species present in each river system. Benthic algae were typically identified as genus or species, and biomass and biovolume were provided for taxa. The U.S. Geological Survey completed data collection in upper White River Basin in cooperation with the White River Conservation District, and the Colorado River data collection was funded...
This dataset includes benthic algae community composition data in the Colorado River near Cameo, Colorado, from 2022-23. Benthic algae were identified as genus or species, and biomass and biovolume were provided for taxa. Data collection was funded by the U.S. Geological Survey Water Mission Area as part of the Next Generation Water Observing System Upper Colorado River project.
This dataset supports the inclusion of Anodontoides radiatus in the genus Strophitus, introducing the binomial Strophitus radiatus. These data also provide strong support for paraphyly in Strophitus and advocate the resurrection of the genus Pseudodontoides to represent the binomials Pseudodontoides connasaugaensis and Pseudodontoides subvexus.

An inventory (enumeration and taxonomic identification) of diet items consumed by wild-caught black carp, based on the examination of gut contents from fish that were collected in the lower Mississippi River drainage of the U.S.
We analyzed morphological and molecular data from one existing and one newly discovered population of 'bullseye' snakehead (Teleostei: Channidae) from Florida. Morphological and meristic data were collected from museum collections and compared with data from recent taxonomic revisions of related species in the 'Marulius' species group from southeast Asia. Additionally, we performed DNA sequencing of COI barcodes from museum tissue vouchers (corresponding with lots examined for morphology) and compared these sequences with an existing COI barcode library for the 'Marulius' group. These analyses were used to determine the taxonomic identity of snakeheads established in Florida.
This data set describes nuclear microsatellite genotypes derived from eleven autosomal loci (Lar24, Lar12, Lar26, Lar19, Rbg13, K16, Rbg18, Hg18, Hg16, Hg25, Rbg29). A total of 651 Larus gulls were examined for this study with samples collected throughout North America, Europe, Russia, and South America.
The widespread distribution of Strophitus undulatus, as well as high intraspecific morphological variation, has led previous authors to doubt the taxon is representative of a single species. Here we provide detailed information for all the freshwater mussels and associated DNA sequence data utilized to test species boundaries in S. undulatus. These molecular data, in combination with morphological data and results from species distribution models, support the recognition of an undescribed freshwater mussel species endemic to streams along the Edwards Plateau in the Colorado River basin in Texas, USA.

The dataset is a composite of morphological data used in the description of a new species of marine fish, Trachinotus macrospilus (Teleostei: Carangidae), endemic to the Marquesas Islands of the Indo-West Pacific. In the addition to the newly described species, three previously named (nominate) species of the same genus are compared and redescribed in this same manuscript. The morphological data include both mensural (morphometric) and meristic (count) data. Synonymies are provided for all species, since many misidentifications have been made in the literature, which dates to the early 1800's.

The North American freshwater mussel tribe Quadrulini has a suite of life history adaptations, however, the evolution of life histories in this group has yet to be explored using comparative phylogenetic methods. Here we provide the AHE DNA sequence alignment representing 27 species from the subfamily Ambleminae that was used to estimate a phylogenomic reconstruction of Quadrulini. Additionally, we provide a compilation of host use information and larval length and height measurements utilized to trace the evolution of life history characteristics, such as larval morphology and host attraction strategy. Phylogenetic trees are presented representing phylogenetic inference performed under Maximum Likelihood, Maximum...

We examined species boundaries within an imperiled group of freshwater mussels in the genus Cyclonaias (Bivalvia: Unionidae) using morphometrics, molecular phylogenetics, and multispecies coalescent models to help guide pending conservation assessments and legislative decisions. Congruence across all lines of evidence indicated that current taxonomy overestimates diversity in the C. pustulosa species complex, while underestimating diversity in the C. nodulata species complex. Here we provide all molecular, morphological, and collection information collected and analyzed in our investigation.
